Pooled Stain Removal

Hi all, 

I hired a 'professional' to stain my deck. I had gotten the recommendation from this site to get the twp1500 series stain- I LOVE the color, love the stain. But the people who applied it totally screwed it up and left stain to pool on the deck and now it is a sticky, gross mess. I am beyond furious as I had to buy ANOTHER 5 gallons of stain because they wasted so much spraying down my deck instead of using a stain pad like I asked them to.  They got it EVERYWHERE- my siding, my bushes, plants, and it looks terrible.  

My question is, how do I remove the pooled stain? Also, am I totally screwed now that the stain has dried that I can't do another coat on top of it since it's not "wet on wet"?  I'm so frustrated. 

Thanks, 

Erin
